If you're not buying into Valentine's Day this year, then you might want to look away – because Love Island's Alex Bowen and Olivia Buckland are sharing the love on Instagram and the cuteness is enough to make you cry.

The couple, who met while living in the famous villa back in summer 2016, are set to wed later this year and are currently making us all feel very single.

Alex melted the hearts of his 1.1 million Instagram followers when he posted a picture of Olivia in a pair of tracksuit bottoms and a red puffer jacket, and his caption will bring a tear to your eye.

"HAPPY VALENTINES! Okay so everyone knows I'm a big soft twat so here goes… but yeah this is what I have to deal with everyday (yes she does have my trainers on) I love this girl," his post started.

"She just doesn’t give a f***, rarely wears make up which I love btw she acts stupid 50% of the time and the other 50% she’s sleeping NO JOKE... but I wouldn’t change her for anything.

"The only thing that’s gonna change is her last name to Bowen in September, then she truly is stuck with me. Normally I plan valentines but today she wanted to do it so I ain’t gonna complain. Happy valentines bishhhh [sic]"

As if that wasn't enough, new! columnist Olivia made a public declaration of love too.

"Soft’o’meter has reached maximum. Happy Valentine’s to my special (special in a weird way) man. I will never grasp how we managed to find each other at the right time in our lives to be so perfectly in sync," she gushed.

"I am so lucky to have someone who is full of patience, gratitude, care & love. Not to mention yo absolutely god damn FOINNNE. You are also annoying & an extreme man child. I love you for that as much as I love you for all of the rest. Let’s get drunk & be weird."

Our hearts.

While Alex and Olivia were set to be the first couple from Love Island to tie the knot, it looks like they've just about been pipped to the post by two lovebirds from last year's gang.
